To all whom t may. concern.'

` Be it known that I, EUGENE F. NIssEN, .a

by fiscal agents in sending money and valu-.

able documents by mail or express. Heretofore it has been practically impossible to design an envelop which could not be steamed open and thereafter re-sealed and it is the principal object of the'present in vention to provide an envelop which is so folded and secured in its folded position that access cannot be obtained to the contents of the envelop without leaving some mark or without in some way mutilating the envelop.

The present invention contemplates the use of an envelop formed of heavy paper or fabric which is so folded that all of the walls will be double and will be gummed and stitched in such a manner as to prevent entering the envelop.

The invention is illustrated by way of eX- ample in the accompanying drawings in which:

Figure l is a view in plan showing the envelop blank kand further indicatingv the gummed portion thereof.

Fig. 2 is a view in plan showing the envelop blank as partially folded.

F ig. 3 is a view showing the envelop blank with its large side-flap folded.k

Fig. i is a view showing the envelop blank with the two side-flaps in their folded and over-lapping position.

Fig. 5 is a view showing the completely formed envelop.

Fig. 6 is an enlarged view showing the envelop after it has been stitched.

Fig. 7 is a view in elevation showing the folded and sealed envelop.

Fig. 8 is a view in transverse section through the envelop on the lines 8--8 of Fig. 7

Fig. 9 is a view in longitudinal section through the envelop as seen on the lines In the drawings, 10 indicates a rectangular front field. At one side of this eld is formed a rectangular side-flap 11, agreeing in dimensions with the front field. At the opposite side of the front field is formeda short rectangular flap 12. This iiap is of the same width as the front field but of a length considerably shorter. A back panel 13 is formedas a continuation of ,one end of the front panel and agrees with the di# mensions thereof. Directly upon thek opposite side of the front panel 10 is a sealing flap L1a. This flapY may be of any desired dimension but is preferably of the same width as the front panel. Formed as a continuation of the side-flap 11 is a safety ap 15. This liap is of the same dimensions as the panel 11 and extends alongside of the back panel 13 whenfthe blank is unfolded. A secondary sealing flap 16 is formed along one edge of the safety flap 15 for a' purpose which will be hereinafter set forth.

In forming the envelop the sealing flap 14 is gummed as indicated at 17. The short side-panel 12 is gummed as indicated at 18 and the back panel is gummed along its op posite side as indicated at 19 and 20. The secondary sealing iap is gummed'on both sides along its opposite edges as indicated at 21 and upon its back as indicated at 22 in Fig. 2. In forming the envelop the safety Hap 15 'is folded along the score mark a and is adapted to fold over to coincide with the side flap 11. l/Vhen in this position the secondary sealing flap 16 will extend upwardly above the edge cf the iiap 11 vas indicated in Fig. 2. The safety and side flap 11 and l5 are then folded over on the score mark o to conform to the front panel 10. After this has been done the short panel 12 is folded over the end of the side-panel 11 and sealed along the gummed surface 18. The two side-fiaps which has thus been sealed together are then covered and completely concealed by the back-flap 13 as indicated in Fig. 5. The two side-flaps and the back iap are then fastened together by a plurality of mechanical fasteners 24 which will be positioned near the marginal edges of the back flap and also at points intermediate. It will thus be seen that the flaps of the envelop will be folded so thatthe auxiliary v will be securely covered by the back flap which is sealed thereto along the gummed surfaces 19 and 20 and further secured by means of the mechanical fasteners.

Vhen the envelop has been thus formed it is stitched as indicated at 25 in Figs. 6`

and 7. This stitching extends from one corner of the auxiliary seal flap along the end of the envelop across the bottom ofthe envelop and up the other side to the opposite corner. The stitching will pass through vthe back flap, ythe auxiliary flap 16 andthe tivo side-flaps. The ends of the thread are intended to be folded over and to be sealed down between the back panel andthe sealing flap when the envelop is closed.

It will be evident from an examination of the drawings and a consideration of the foregoing specification th at an envelop Will be provided which is practically secure against any sortof manipulation of the flap or panels whereby access to the interior of the envelop could be obtained, yit being further noted that due to the fact that all of the exposed edges of the finished envelop are stitched and thatthe ends of the thread are secured lin a sealed position beneath the flap L7, that any effort to remove this stitchingor to substitute other stitchingtherefor, would be fuseless.

Having thus described my invention, what I claim and desire to secure by Letters Patent is: a

An envelop composed of a front panel, opposite side lflapsborne thereby, a back panel connected to the bottom of the front panel, a sealing flap connected to the top of the front panel, a safety flap connected to the bottom of one of the side flaps, and a secondary sealing ,Hap connected to the bottom of the safety flap, the safety flap beingfolded onto said side `flap vand the second# airy sealing flap being gummed onto the inainfseali-ng flap, Athe back panel 'being superimposed upon the safety vand other side flap, and both sealing flaps being gummed onto the `back` panel, and stitching extending around the bottom and sides of the back panel and through the latter and through the secondary sealing flap and the tivo side flaps, the ends of the thread extending out from the secondary .sealing `flap and being foldedito lie between Athe latter and the back panel. n
